SPECIFICATION forming part of Letters Patent No. 296,929, dated April 15, 1884.

Application tiled July 25, 1883. (No model.)

To @ZZ whom t may concern:

Be it known that I, AMBRosE S. CRoX'roN,

a citizen of the United States, residing at Cedar Springs, in the county of Kent and State 5 of Michigan, have invented certain new and useful Improvements in Stump Extractors; and I do declare the following to be afull, clear, and exact description of the-invention, such as will enable others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specication.

r 5 Figure 1 of the drawings is a side view. Fig.

2 is a top View. Figs. 3, 4, 5, and 6 are detail views.

This invention has relation to stump-extractors; and it consists in the construction and novel arrangement of parts, as will be hereinafter fully described, and particularly pointed out in the claims appended.

Referring by letter to the accompanying drawings, c designates the frame of the hoisting-machine, which is composed of two shears, b and b', mounted on runners c c', and bound near their upper ends by wire bands d d. Eyebolts d2 have their shanks passed through the upper ends of the arms ofthe shear b from the inside outwardly over the inner side of the band d and underthe outer side of the same, and secured in place by nuts on the threaded ends of the shanks. The eyebolts' d3 have their 'shankspassed through the arms of the shear b and band d', but their shanks are longer, and are provided with sleeves c, against which a plate, c, on the end of the rod e2, which supports the pulleyshear f, secured to the shear b, abuts, and is held in place by nuts f. The eyebolts'dL and d3v and the eye at the upper end of the -hangerrod g are hinged on a single pintle, g', held in place by cross-pins passed through it at each end, thereby connecting the shears b and b together.V When the frame a has been hoisted to its proper elevation, brace-rods h 71J connect the opposite arms of the shears b and b at points about midway of their length.

i designates the hoisting-lever, which is 5o made partly of iron and partly of wood. The

metal portion of this lever i is made from a dat bar of iron, which may be first notched and perforated and then cut diagonally in two equal' parts, as shown in the drawings, thereby forming both sides of the open portion c" of the lever. The wooden portion i is made of planks or strips, one of which fills the space between the iron sides for a portion of their length, the others being on the outsides of the iron sides. Strips i3, of the same thickness as 6o the iron bar, are let into the spaces formed by letting the tapering ends of the iron bars extend back the full length of the lever, and the parts are secured together by rivets or bolts and an encircling iron band, 4, near the power end of 65 the lever. The front end of the lever z' is pivoted to the lower end of the hanger g, inside washer, j, being employed on the pivot to prevent wear. The rear end of the lever t' is provided with a hook, k, to engage the eye of 7o the lower pulley-block, k. The upper pulleyblock, k2, is suspended from a hanger, k3,V on the rod el at the upper end of the pulley-shear. The guide-pulley Z is hooked into a staple, Z',

in one of the runners, as shown. A hanger- 75 rod, m, made considerably shorter than the hanger-rod g, depends from the inner side of the band d, and is provided at its lower end with a pivoted clutch-block, m, consisting of two side plates and a rectangular cross- 8o pin, m2, connecting their lower ends, and leaving a sufficient space between the side plates for the liftingbar q to work in. A short movable hanger, o, having a cross-pin, o',

at its upper end to iit the notches o2 in the 85 upper edges of the side bars of the lever i,

is provided with an eye, p', in its lower end,

is dropped through the space between the iron side bars of the lever i until'the pin rests upon the notched edges of said bars, and is 9o provided with a pivoted clutch-block, p, similar in construction to the clutch-block m. The lifting-bar q is provided with angular notches in one of its edges, which may be cut by machinery very cheaply, and owing to their form may be made very closely together. The lower end of the lifting-bar q is provided with a hook, q', to engage the load to be lifted, and

in rear of the hook-point a hole, q, is punched,

to forni a fastening for a chain, where one is roo desired to be used. The lifting-bar q is passed up through the lower clutch-block, p2, then between the iron side bars of the lever, then through the upper clutch-block, m, and finally Y late e this guide beinO1 intended to revent tipping forward or swaying of the upper end of the lifting-bar gf. 'Vhen the load to be hoisted has been attached to the hook, the

power end et the lever being lowered until the cross-pin o of the short hanger o is in the lowest notches of the iron side bars-that is, the notch nearest the wooden portion o the leverthe rope is operated to lift the power end of the lever, and it may be lii'ted to its fullest extent. This carries the lower clutchblock, p2, upward, and as its rectangular crosspin engages the lower notches of the liftingbar q, the latter is moved up through elutehblock m on the hanger m. By releasing the draft on the rope, the weight of the lever will cause its power end to descend, and at the moment it commences to descend, the clutchblock p2, being pivot-ed to the short hanger o, releases its bite upon the notches of the lifting-bar, and the cross-pin et' the upper clutchblocl, m, engages them and holds the liftingbarin the position to which it has been raised. If it is necessary to lift the weight higher, dthe power end of the lever should be again raised, when the pin 0 of the short hanger o will be carried to the next notch in the lever, and the lifting-bar will be again moved up through the clutch-block m, and thus on until thelast or uppermost notch in the lever has been reached. ln some instances l may use a round rod, l, having two friction-rings, 2 and 3, each provided with an annular dog, ft. The dat bar should then be removed.. The dogs -i ot' the rings 2 and 3 are to engage the cross-pins ofthe clutch-blockspL and m', and the rod is to be passed up through the former, thence be tween the side bars ol" the lever, and thence through the upper i'rictionning, 3, and also through the guide at the top of the frame.

This construction works well and is cheaper, but the dat bar is preferable, owing to the fact that in wet weather the friction of the rings on the rod is considerable.

The lever herein described works admira bly, but I have found that can employ a construction which is more economical and works equally as well. The major portion of this lever A is ot' wood. it is bi'urcat-ed at its forward or weight' end, and is provided with a bifurcated metal thee-plate, B, on this portion, as shown in the drawings. A forked bearing, C, carries a pivoted hanger, D, at its forward end, which depends through the bifurcation in the lever n, and is provided with a rack-stem, E, which passes under a ratchet wheel, F, working in bearings on the top of the lever near the bil'nrcaed plate, as shown. This ratchet has a pivoted linli-pawl, l and the shaft of the ratchet-wheel is provided with a crank, l, by which the rack and forked bearing carrying the hanger may be moved baci; and forth at will. When this lever is in place, its weight end is suspended from the hangerrod g and its power end is connected to the lower pulley-block, as shown for the other lever.

The lower'end or" the hanger D is provided with an eye, K, to which the lower clutchblock, p2, is pivoted, and the lifting-bar q is passed through the clutch-blocks, lever, and guide, as in using t-he other lever. The lifting-bar in this case will be run out or in by lifting the pawl and turning the crank in the desired direct-ion. When the lifting-bar is in the desired place; the pawl may be dropped, and will loci; it there. When the frame of the machine is extended before being elevated into position, it is nearly horizontal. The manner in which the shears are connected at their tops enables me to raise it into position very easily by means ot' the pulley-block and horsepower attached to the rope..

llaving thus described my invention, what l claim as new, and desire to secure by Letters latent, is-

l. The combination, with the shears I), mounted on the runners c, and provided at their upper ends with the eyebolts d2 and band d, oi' the shear Z2', mounted on the runner c, and provided at its upper end with the eyebolts d, band U, having projecting shanks carrying the sleeves c, and plate for forming the guide, and the pintle g', for connecting the eyebolts d'l d and suspending the hanger-rod g, substantially as specified.

2. The combination, with the shears b of the traine c, having the rod e, connected to the plate c of the lil'tingbar guide, ot' the pulley-shear connected to the rod e2 and to the shears o', substantially as specified.

8. The combination, with the frame a, provided with the hanger-rod g, pivoted to the tulcral end ot' the hoisting-lever, the rope and tackle tor operating the power end of said lever, and the pulley-shear, of the hanger-rod m, provided with the pivoted clutclrblocl; m', the short hanger o, carrying the cross-pin o at its upper end and the pivoted clutch-block p at its lower end, and the notched liftingbar (j, provided with the hool: and the perforation in its lower end, said lifting-bar passing through the clutch-blocksp2 m', the space between side bars ot' the leverI t', and through the guide at the top of the frame, substantially as specified.

4.-. The round rod having the friction-rings and dogs, adapted to engage the clutclrblocks, the rod to pass through rings and between the iron side bars ol" the lever z', substantially as specied.
